RECOIL-REGISTER.

Speccaton of Letters Patent.

Patented Aug. 1*?, 1915.

Application filed I une 28, 1915. Serial No. 36,481.

T0 alla/17mm it muy concern Be it known that I, GUsrAv Gr. Goonn, a citizen of the United States, residing at York, in the county of York and State of Nebraska, have invented certain new and useful Improvements in Recoil-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to registers, and more especially to the means for operating the same; andthe object of the invention is to register the number of shots fired vby a gun. This object is carried out by providing means for mechanically counting the recoils `of the gun, by which latter term as used in this specification I desire to be understood as including not only the ordinary rifle and fowling-piece `but machine guns and larger pieces of ordnance to which the invention maybe readily adapted. `Registers of this character have hitherto been attached to or inserted in the gun-stock and actuatedl by the trigger or by tne recoil. In thevformer instance the devices are not accurate, because occasionally the trigger is moved `without firing the gunand therefore there `is no recoil. rIlhose devices which actuate the counter by recoil have always, as far as I am aware, `exposed the face of the counter through the side of the gun-stock. I consider this objectionable because the counter should be in the upper edge of the gun-stock where it is .more readily exposed to view and less liable to accidents. I overcome this and other objections by constructing my invention in the manner hereinafter described and claimed and shown in the drawings wherein Figure 1 is a plan view ofthe rear end of a gun-stock equipped with this `*recoil register. Fig. 2 is an enlarged central longitudinal section through the `gun-stock and the casing of my invention, showing the parts in full lines in normal position and in dotted ylines in the position that they assume at the moment of recoil. Fig. 3 is a rear elevation of a gun-stock equipped with my invention, the shoulder plate being turned aside. Fig. i is a perspective detail of the frame. Fig. 5 is a perspective detail of the rocking pin.

In the drawings the letter G designates a gun which might be a machine gun or a larger piece of ordnance, although in the present instance I have shown only the rear end or the stock of an ordinary shot gun or the like, the lsame being generally made of wood and having a shoulder plate P Vsecured to its rear end by screws S or otherwise. The letter C designates a registering mechanism, such for instance as the Veeder counter, to whose details of construction no claim is made; and it is quite obvious that any other suitable counter could be employed in its place.

Coming now to the details of the present invention, I provide the gun-stock with a chamber 1 opening out its rear end at 2 so that it may be covered by the plate P when the latter is fastened in propr-r position, and having an opening through the top or upper edge of the stock covered with glass 3 so that the counter C may be seen therethrough. As seen in Fig. 3 the upper portion of this chamber is made substantially tubular, and its rear end has a notch or recess l to receive the foot 5 of the frame 6, which foot may be held to the stock by screws 7. Said frame is preferably formed of a single piece of metal bent to the shape best seen in Fig. 4, its body being provided with slots 10 and 11 set oblique to its length and at an angle zto each other, its front end 12 `being upturned and pierced with an eye, and its rear end 13 being also upturned and provided with a socket, and carried down into said foot 5. Mounted in saidsocket 13 is the rear end of a rod 15 which passes completely through the counter C and eX- tends through the eye in the upturned front end 12 of the frame, and this end 'of the rod has a long thread 16 cut thereon as seen in big. 2. On this thread run barrel nuts 16 and 1.7 resting against opposite sides of `the front end 12 of the frame, whereby the rod is held removably and adjustably in place. This rod forms a guide for the longitudinal movement of the counter and the rocking pin described below.

Depending from the casing of the counter is a pin 21 niovably engaging the rear slot 11, while a rocking pin 20 has its lower end movably engaging the forward slot 10 and its body connected with a tubular shaft 22 which surrounds the rod 15 and extends into and is connected with the mechanism for advancing the unit wheel of the counter step by step. I have not illustrated in detail how this connection is effected, first because it forms no part of my invention, and Second because the connection may have to be varied toadapt it to different types of counters. `It

is only necessary that an oscillation of the tubular shaft with respect to the casing of the counter will actuate the latter. rlfhe upper end of said rocking pin is preferably split as at 23 and passed astride the tubular shaft, its arms being drawn together upon said shaft by means of a screw 24. A long and extremely sensitive coiied spring 25 surrounds the rod between the rocking pin and a head 26 on the forward end of the reai` lbut quick recoil. of the stock which of courseA carries with it the frame, while the counter on account ofits inertia tends to remain stationary. The result is that the forward slot l0 moves over the lower end of the rockingpin 2O and swings it to one side, while the rearward slot 1l moves over the pin 2l and swings the casing of the counter C in the` opposite direction. The tubular shaft to which the rocking pin isattached is therefore oscillated withrespectl tother casing,

and the unit lwheel of thefcounter is set forward one step as is common in devices of this character. The rearward movement of the upturned front end l2 of the frame also causes the compression of the spiral spring,v

and as soon as the force of the" recoilhas spent itself this spring expands and restores the parts to their original position. Meanwhilethe dial or face of the counter has moved slightly forward from the position shown irrl'h'g l and out of registry with the hole, but immediately resumes its proper position thereunder', and the marksman or hunter canlook through this hole at any time andobserve how many shots have been tired'. This-register is'made, as above stated,

by means of the recoil rather than by movements of the trigger, and is therefore quite reliable. lt will be observed that should the Abutt of the stock be dropped on the ground,

the register will not be actuated; and it is hardly likely that the open end of the barrel will ever be rammed against anything with sufficient force to-actuate the mechanism described. While I have shown'the frame as provided withtwo oppositely inclined slots (or they might be merged into a single slot made angular between its extremities) so that the counter turns in one direction and the pin in the other, it will hardly require further illustration to make it clear that if either the counter or pin were turned to a greater degree the other element need not turn at alliY l-owever, I prefer the construction shown for the reason that a single oblique slot would require the frame to be somewhat wider, and a widerframe woul necessitate a chamber of such size that it might weaken the gun stock.

What claim is: l. VA recoil register for guns comprising a frame adapted for attachment to the gun stock and having an oblique slot, avlongitudinal guide carried by said frame, a counter. including a tubular actuating shaft slidably mounted on said guide, yielding means for holding the counter at the rear end of the frame, Yand a swinging pin having one end secured to said shaft andthe other end'mounted in said slot.
